    Cheers, yes thanks. It makes sense. I've got a plumber tomorrow so the pipes in the proximity will get dealt with The as it's about time to get the radiator back in working condition. The pipe joints seem bone dry though so if there's a leak it's not from there.

    It could be higher up, the plumber will hopefully help you eliminate the pipes

    You'll get it sorted one way or another and your experience and solution to your problem is helpful to other people should they have similar issues

    what nonsense assertions sometimes appear in these threads:

    1. a "plumber" who supposedly turns out on sundays for a non urgent bit of pipe.
    2. two rocket scientists who see rising damp coming down from on high.
    3. one scientist claims that ground water is a result of high level leaks - "the water pools".
    4. "the majority of damp is high level" - is it? is this a recent thing? someone should alert the Remedial trades.
    5. the other scientist asserts "Majority of damp originates at high level and falls thru brickwork until it hits dpm ... " well considering that , in this thread, no DPM is present, and DPM's go under floors not in the "brickwork".
    6. fwiw: DPC's go in the "brickwork".

    Plumber is someone i know personally so he does comes to do work for me on random days. There's no issue with pipes and leaks.
    Dpc goes in the mortar between brickwork. At least the one I'm using - that's in the official instructions. I know that mostly in the past they would inject the bricks but it's currently mostly avoided.

    No such thing as rising damp , water falls, it’s called gravity.
    There is still an unclaimed reward for anyone who can prove rising damp i.e under lab conditions .

    5 and 6 seem to be complete contradiction of each ?

    a liquid, gas or any collection of particles would move from a region of high concentration to a region of low concentration by e.g. diffusion, even against energy barriers e.g. gravity. Stick one end of a shoe lace in water, and water would climb up the lace until a new balance is reached, e.g. when the number of particles going up from the wet side of the lace to the dry side due to diffusion become equal to those particles going down due to gravity. Essentially this is what rising damp is.

    The real question is what caused the soil there to be wet and i think it's heavy rain in the region saturated all clay soil everywhere. Given my house is very old and my floor level is only two bricks higher than the level of the garden, any water rising would have a very small distance to travel.

    OP, fair enough, i apologise.
    but why did you vanish from your own thread?
    what has happened during the last four days?

    DPC's are built into the walls - modern DPC's come in rolls of plastic. your method of gun cartridge cream has yet to be tested over a long period on sites, but its probably the best remedial method available at the moment.

    if you ignore the advice i was suggesting (you cut me off before i had finished) you will undoubtedly have to deal with further rising damp issues. there's more suggestions if you want?

    ignore the two guys posting foolish stuff - their nonsense has got as much validity as a flat earth theory.

    I'm filling the hole with gravel but the gravel is wet so i move a bucket inside, wait until it dries and then throw it in the "well". I'll leave it open for another week or so whilst I'll be away for a trip. Once I'm back I'll add a plastic sheet and then more gravel, fill it completely flat with the rest of the floor. Then one more plastic sheet, underlay and then laminate to redo the floor.

    I'll have to replaster the regions I destroyed. So that would come next. At that stage I'll have to think which player is best for my case. And I'll make sure it will not touch the floor, just in case the floor is ever damp again.

    you claimed in post #27 that the ground water is "High level leak and the water is pooling at the bottom of your hearth".

    If I remember rightly when they tested rising damp in a lab by sticking a brick column in a pool of water they noticed that the rising water wouldn't go any further than one meter high , been a few years since I remember this however
